FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION formingpart of Letters Patent No. 271,114, dated January 23, 1883.

Application filed May22,1882. (NomodeLl To all whom it may concern:

Be it known that I, THOMAS POWELL, a citizen of the United States, and a resident of Chester, Delaware county, Pennsylvania, have invented an Improved Fan Attachment for Rocking-Chairs, of which the followingis a specification.

One object of my invention is to so construct the fan and the operating mechanism therefor that the action will be direct and the parts few and of the simplest character, a further object being to cause a more extended swing of the fan than usual without the use of gear In the accompanying drawings, Figure 1 is a perspective view of a rocking-chair with my improved fan attachment; and Figs. 2, 3, and 4, rear views of part of the attachment, showing the fan in different positions.

A is a rocking-chair of ordinary construction. To one of the side bars of the back of the chair is secured a rod, B, bent at the up? per end to form a yoke, D, in which is journaled a shaft, a, secured to or forming part of the fan F. A coiled spring, I), surrounds this shaft, one end of the spring bearing against the fan and the other end against the rod B, the tendency of this spring being to maintain the fan in the position shown in Fig. 2, or to restore it to this position after it has been moved therefrom.

To the end of the shaft a is secured a lever, d, the short arm of which has a projection, e. and over the latter passes a cord, f, one end of which is secured to the end of the long arm of the lever, the other end being secured to the longarln of a lever, G, pivoted to one of the rockers of the chair, so thatits short arm will bear upon the floor. When the chair is unoccupied and in its normal position the fan, fanshat't, and lever 61 are in the positions shown in Fig. 2. When the chair is tilted backward, however, the lever G will be actuated, thus imparting a pull to the cord f, the first. effect of this movement being to depress the short arm of the lever d, owing to the fact that the cord f passes over the projection e on said arm.

The shaft a is thus caused to rotate, and the fan F swings inward and downward, as shown by the. an row, Fig. 2, the pull of the cord being exerted upon the short arm of the lever (1 until the latter assumes the position shownin Fig. 3, when the pull is transferred to the long arm of the lever, and the movement of the latter is continued until the parts reach the position shown in Fig. 4, the rocking-chair having then reached the extremity of its rearward movement. As the chair rocks forward the coiled spring 7) tends to restore the parts to their original positions, as shown in Fig. 2, prior to a repetition of the operation.

It will be observed that the operating parts of the device are of the simplest character, and that the actions aredirect and positive, the device being therefore inexpensive in construction, easy to apply, and not liable to get out of order.

The formation of the projection 6 upon the short arm of the lever d is a valuable feature of my invention, as it permits a movement of the leverd throughout about three-quarters of a circle, whereas if the cord f were connected directly to the end of an arm on the shaft the movement would be limited to less than half of a circle, and the pull of the .cord would be exerted at a disadvantage at and near the commencement and close of the movement.

I claim as my invention- 1. The combination of the chair with the rod B, having a yoke, D, the fan F, its shaft or, spring I), and leverd, theleverGr, hung to the rocker, and the cord f, connecting said levers d and G, as set forth.

2. The combination of the fan-shaft,the lever d, the short arm of which has a projection, c, and the operating-cord f, connected to the long arm of the lever and adapted to pass over the projection e, as set forth.

In testimony whereof I have signed my name
